How can I loop through all my asp:lables inside my asp:tables? I need to check every label on my page and see if the text inserted from our database says a specific word. If the word is what we are looking for, I change the forecolor of the word in the asp:label to Red.

Given a normal WPF Window object, I want to walk the list of all controls contained in that Window and find all objects of a specific type...i.e. all of my UserControl objects that were placed in the XAML definition of that Window.ÃÂ What's the best way to do that?

I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.

1. If there are existing records in the table - works fine and sets my two values:I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.

2, If ther are not records in the table - saves record but cannot find and set controls on the detailsviewSame thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.

I have a JQuery date mask, but when I run the page it throws an error "Microsoft JScript runtime error: Object doesn't support this property or method".

Now, the control that this particular JQuery is meant to be working is added dynamically to a repeater control. Through this, I have looked at the ids of the control, where it was breaking and stopping in Visual Studio and what is being shown on the aspx page. The ids are identical except of the "#" that JQuery has at the start, which is not on the page.

In this interview, programming writer, McLean Schofield, demonstrates how to bind WPF controls to an entity data model, using Visual Studio 2010 Beta 1. You can also learn more in the topic: Walkthrough: Binding WPF Controls to an Entity Data Model.

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

how we can access a particular control which resides inside a GridView control. In this article I will show you how you can access different controls inside a GridView control. We will see how we can access a TextBox control, a DropDownList control and a ListBox control. If you are working with ASP.NET 1.X then you might want to check out my article Accessing Different Controls Inside a DataGrid.

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.
